The ashes and butts 29 in the ashtray 22 fall downward from the drop holes 23 in the ashtray 22.

At the position of the opening 3 in front of the lift 4 for pachinko ball collection, a removable slat 6 is detachably provided so as to coincide with the slats 5 in front of the left and right pachinko machines 2. As shown in FIG. 3, the removable slat 6 is formed between the left and right slats 5 by, for example, a sliding guide between a convex guide 24 on the end face of the slat 5 and a concave guide 25 on the slat 6. It can be removed from the left and right side plates 5. The positional relationship between the convex guide 24 and the concave guide 25 may be reversed with respect to the saddle plates 5 and 6.

A screw case 8 is detachably provided on the lower surface of the flange plate 6 so as to match the screw cases 7 of the left and right flange plates 5 and is removable. In this example, the screw case 8 is formed as an upward U-shaped cross-sectional shape by an aluminum molded product, for example, and is elastically deformed with respect to the base 27 attached to the lower surface of the plate 6 as shown in FIG. Fits detachably. The screw cases 7 and 8 are arranged on one line by the fitting of the plate 6 with the left and right plate 5.

In this example, the screw cases 7 of the left and right ribs 5 are also detachably fitted to the base 26 by elastic deformation, like the screw case 8. Thus, since the screw cases 7 and 8 and the bases 26 and 27 are aluminum molded products having the same shape, they are advantageous in production. In addition, the connection of the screw cases 7 and 8 is a butting of cut surfaces. When ash leakage from the butt connection position is predicted, a sealing tape or the like is attached to the outside of the butt position. Of course, the connection of the screw cases 7 and 8 may be a stepped butting.

As shown in FIG. 3, two screws 9 are inserted into the left and right screw cases 7, and one screw 10 at the position of the opening 3 is detachably inserted into the screw case 8 at the intermediate position. . As shown in FIG. 4, these screws 9 and 10 are constituted by a plurality of screw parts 16 having a short length, and the necessary number of screw parts 16 has a central hole 17 formed on the screw shaft 11 or the screw shaft. 12 is integrated by frictional insertion. In this example, the screw parts 16 have two screw blades, but the screw blades may be configured as one or three, four, or the like.

The removable screw 10 at the intermediate position is detachably connected to the left and right screws 9 by left and right shaft joints 13, respectively. In this way, the three screws 9 and 10 are accommodated in a straight line inside the linear screw cases 7 and 8 on the lower surfaces of the flange plates 5 and 6.

Next, FIGS. 5 and 6 show specific examples of the shaft joint 13. First, the shaft joint 13 of FIG. 5 includes a diametrical engagement groove 18 extending in the axial direction of one screw shaft 11 as shown in FIG. 5 (1), and the other as shown in FIG. 5 (2). And a ball plunger 19 fitted in the engaging groove 18 in the diameter direction of the screw shaft 12. When they are fitted, as shown in FIG. 5 (3), they are prevented from coming off in the axial direction due to the engagement between the recess 30 of the engagement groove 18 and the ball plunger 19.

Further, the shaft joint 13 of FIG. 6 includes a diametric fitting groove 20 extending in the axial direction of one screw shaft 11 as shown in FIG. 6 (1), and the other as shown in FIG. 6 (2). And a pair of fitting pieces 21 fitted in the fitting groove 20 in the diameter direction of the screw shaft 12. The pair of fitting pieces 21 are always open with elasticity, like Japanese scissors (nigiri rice bowls), but squeezed when inserted into the fitting groove 20, but when reaching the insertion position, ( As shown in 3), the hook-shaped portion falls into the recess 31 and opens to be in a retaining state. When pulling out, pull out while pushing with the pusher 32.

The three screws 9 and 10 connected by the two shaft joints 13 are in contact with the inner surfaces of the screw cases 7 and 8 by the lower ends of one or two or more screw blades by their own weight. One end of the screw shaft 9 on one side of the screw case 7 is connected to a free shaft joint 28 or the like as needed to transfer the ash and butts 29 dropped into the screw cases 7 and 8 from the drop hole 23 of the ashtray 22. Thus, it is connected to a rotational drive source 14 such as a motor. Also, a butt collection box 15 is provided below the opening position of the screw case 7 on the downstream side in the transfer direction of the butt 29.

Next, the operation of the cigarette butt collection device 1 for a pachinko machine will be described. During the operation of the pachinko machine 2, the rotational drive source 14 rotates the screws 9 and 10 in the transfer direction to recover the cigarette butt 29, and falls into the screw cases 7 and 8 by the rotation of the screw blades. The ash and cigarette butt 29 are transferred in the direction of the butt collection box 15 and are continuously dropped from the opening position of the screw case 7 into the butt collection box 15.

On the other hand, during operation of the pachinko machine 2, the lift 4 collects pachinko balls falling from the left and right rows of pachinko machines 2, raises the pachinko balls to a high supply position while polishing them, and Distribution to machine 2. The lift 4 is maintained and inspected for a certain period, for example, in a monthly cycle, at night when the pachinko machine 2 is not operating.

When maintaining and inspecting the lift 4 for collecting pachinko balls, an operator first removes the screw case 8 from the base 27 at the position of the opening 3, and then performs the operation of separating the shaft joints 13 at both ends of the screw 10. Then, after removing the screw 10 from the screws 9 at both ends, the hook plate 6 is pulled forward, and the hook plate 6 is removed from the left and right hook plates 5. By these removal operations, the front surface of the opening 3 is completely opened.

In the operation of separating the shaft joints 13 at both ends of the screw 10, the screw 10 is moved in the axial direction within the range of the insertion allowance of the shaft joint 13, but the screw 9 on the side of the butt collection box 15 is Since it is not restrained in the axial direction, the worker moves the screw 9 together with the screw 10 in the axial direction, and pulls the screw 10 out of the other screws 9 to separate them.

By the above-described removal operation, the front surface of the opening 3 is completely opened. Here, the worker pulls out the pachinko ball collecting lift 4 from the position of the opening 3 to the front, and performs maintenance and inspection. After the maintenance and inspection are completed, the worker returns the lift 4 to the position before pulling out, and then reverses the order of the removal work, that is, the installation of the cover 6, the installation of the screw 10, and the installation of the screw case 8. To complete the maintenance and inspection work.

The screw shafts 11 and 12 are manufactured as an extruded product of an aluminum material so as to be frictionally fitted into the center hole 17 of the screw part 16. For this reason, as shown in FIG. 5, when the ball plunger 19 directly hits the engaging groove 18, it is predicted that the engaging groove 18, the recess 30 and the like are worn away.

The shaft joint 13 shown in FIG. 7 is an improvement plan for preventing wear, and a hard metal material such as stainless steel auxiliary shafts 37 and 38 are fitted into the screw shafts 11 and 12 by fixing means such as press-fitting. In this example, an engagement groove 18 is incorporated in one of the two, and two ball plungers 19 are incorporated in the other as an example. When the auxiliary shafts 37 and 38 are fixed, a split pin, a tapping screw or the like (not shown) is used instead of or together with a fixing means such as press-fitting. According to this example, it is possible to prevent wear of the engagement groove 18 and the recess 30 in advance. Although not shown, the auxiliary shafts 37 and 38 for preventing wear can be applied to the shaft joint 13 shown in FIG.

Further, the shaft joint 13 of FIG. 8 includes a diametrical projection 33 formed on one of the screws 9 and 10 and the screw shafts 11 and 12 to be coupled, for example, the screw 9 and the screw shaft 11, and the other screw 10 and screw shaft. 12 diametrical projection grooves 34 that fit into the projections 33, locking pins 35 such as cotter pins and pin holes 36 that prevent the mating projections 33 and the projection grooves 34 from coming off. It is an example composed of Since the diametrical projection groove 34 is open at least at one end, the projection 33 fitted therein can be inserted and removed from the open portion of the projection groove 34. This insertion / extraction is performed when the screw 10 is separated from between the left and right screws 9 as will be described later.

According to this example, the screw shafts 11 and 12 are moved in the axial direction by removing the retaining pin 35 from the pin hole 36 and removing the projection 33 and the projection groove 34 in the diametrical direction without sliding them in the front-rear direction (diameter direction). Therefore, since the screw 10 can be separated from the left and right screws 9 at the position of the opening 3, the separation operation can be easily performed. The separation of the screw 10 is an operation in the same direction as an operation of pulling out the saddle plate 8 from between the left and right saddle plates 7.

In the above-described specific example, the configuration for enabling the detachment of the slat 6 is not limited to the above, and the slat 6 can be removed from the left and right slats 5 by sliding upward. . In addition, the shaft joint 13 may be a specific example as long as it has a structure capable of transmitting rotation between the two screw shafts 11 and one screw shaft 12 and separating them as necessary. There is no limitation, and other structures can also be used.
